Switch skipping frames only in 1080p mode

My Nintendo switch skips/rewinds/stutters for around 4 frames every few seconds. It only shows up on my monitor and not my capture card. It was like this since I bought the console used.
I have tried different HDMI cables and using other devices at 1080p60hz with the same HDMI cables on my PC and it’s not skipping frames. I tried OEM and 3rd party dock and the problem persists.
720p mode works perfectly fine. I’m lost on what to do or what to try or test.
